进入到新世纪以来,随着我国的市场经济水平的十分迅速的提升,我国的城市化的进程也在不断的加快,其中城市天然气管道的建设工作是一项非常重要的基础设施,而在天然气管道工程场站工程的施工过程中,工艺管道试压后的干燥是一道十分关键的工序,其干燥的质量对后续的运行和维护工作也有着决定性的影响。以往普遍采用的都是热空气干燥技术,这项技术通常都被专业的干燥公司所垄断,施工周期非常长,并且需要投入的成本也较高,与热空气干燥法相比,热氮气干燥施工技术具有更明显的优势,其施工的成本更低,并且大大的缩短了工期进度,因此,在站场工艺管道的干燥施工过程中,热氮气干燥施工技术具有更加优异的应用价值。本文便对热氮气干燥施工技术的独特优势、热氮气干燥技术的施工工艺流程以及热氮气干燥施工技术中的安全保护要求三个方面的内容进行了详细的分析和探讨,从而详细的论述了站场工艺管道施工中的热氮气干燥施工技术。
Since entering the new century, with the rapid improvement of the market economy in our country, the process of urbanization in our country is also accelerating. The construction of urban natural gas pipelines is a very important infrastructure. In the natural gas During the construction process of the pipeline engineering station project, the drying after the pressure test of the process pipeline is a very crucial process, and the quality of the drying also has a decisive influence on the subsequent operation and maintenance work. In the past are generally used hot air drying technology, the technology is usually monopolized by a professional drying company, the construction cycle is very long, and the cost of investment is also higher, compared with the hot air drying method, hot nitrogen drying construction technology Has more obvious advantages, the construction cost is lower, and the progress of the project is greatly shortened. Therefore, the hot nitrogen drying construction technology has more excellent application value in the drying process of the station process pipeline. In this paper, the unique advantages of hot nitrogen drying construction technology, the construction process of hot nitrogen drying technology and the safety protection requirements of hot nitrogen drying construction technology are analyzed and discussed in detail. Construction Technology of Hot Nitrogen Gas Drying in Construction Process Pipeline.
